PENDULUM-IBOB.

Application filed November 29, 1913.

To all whom it may concern:

Be it known that I, Gnoncn H. MILLER, a citizen of the United States,residing at Lima, in the county of Adams and State of Illinois, haveinvented new and useful Improvements in Pendulum-Bobs, of which thefollowing is a specification.

This invention relates to pendulum bobs, the object in view being toprovide a bob having a section detachably connected to the remainder ofthe bob and threaded on the rod, so as to be adjusted up and down on therod and held against rotation by means of the major portion of the bob,when brought into its proper relation to the removable section, thedevice being intended as a whole for adjusting the bob up and down onthe rod in order to regulate the clock mechanism.

\Vith the above and other objects in View, the invention consists in theconstruction, combination and. arrangement of parts, as will behereinafter more fully described, illustrated in the accompanyingdrawings, and pointed out in the claim hereunto appended.

In the drawings: Figure 1 is a front clevation of a pendulum hob androd, showing the normal relation of the two parts of the bob. Fig. 2 isa similar view, showing the major portion of the bob elevated, in orderto enable the smaller section thereof to be adjusted on the rod. Fig. 3is a vertical section through the bob taken in line with the rod. Fig. 4is a detail view of the removable section.

Referring to the drawings, 1 designates a pendulum bob, and 2 the rod bywhich said bob is carried.

In carrying out the present invention, the

Specification of Letters Patent.

Patented Mar. 14, 1916.

Serial No. 803,839.

bob 1 is provided with a removable section 8 in the lower edge or marginthereof, and said removable section 3 is internally threaded so as toscrew upon the lower end of the rod 2, which is also threaded, as

shown at 4:.

In order to adjust the bob 1, the larger section thereof is slid upwardon the rod or stem 2, and the smaller section 8 thereof is then threadedupward or downward on the rod i, a suitable distance, after which 1 othe larger sectlon 1 of the bob 1s lowered until it encompasses thesmaller section 3 thereof, which acts as a lock for the section 3 andprevents the latter from turning on the rod, thereby fixing theadjustment. It will thus be observed that it is a comparatively easy andsimple matter to adjust the bob as a whole lengthwise of the rod 2, forthe purpose of regulating and timing the clock movement.

What is claimed is:

The combination with a pendulum rod, of a circular bob embodying a mainsection formed with a recess in the margin thereof, said recess havingtwo parallel sides. and a removable bob section threaded and adjustableon said rod, the main section of the bob being slidable on the rod inorder that the two sections may be entirely separated one from the otherto enable the smaller section to be turned on the threaded rod, both ofthe sections when in their useful po sition having flush surfaces.

In testimony whereof I affix my signature in presence of two witnesses.
